 <p><a href="https://github.com/rootless-containers/rootlesskit"><code>RootlessKit</code></a> is the <em>fakeroot</em> implementation for supporting <em>rootless mode</em> in Docker and Podman. By default, RootlessKit uses the <a href="https://github.com/rootless-containers/rootlesskit/blob/v0.14.5/docs/port.md#port-drivers"><code>builtin</code> port forwarding driver</a>, which does not propagate source IP addresses.</p>
 <p>It is necessary for F2B to have access to the real source IP addresses in order to correctly identify clients. This is achieved by changing the port forwarding driver to <a href="https://github.com/rootless-containers/slirp4netns"><code>slirp4netns</code></a>, which is slower than the builtin driver but does preserve the real source IPs.</p>
